Those of you who have asthma to varying degrees, would you mind telling me what kind of exercises you're doing and how you're dealing with your asthma when you do it?

I walk, jog, and do a little strength training. The cardio would be impossible on bad asthma days without my inhaler, to be honest. I'm not in a position to give any medical advice so I'd strongly recommend seeing your doctor to discuss ways to manage your condition. You really don't want to mess around and end up giving yourself a bad asthma attack trying to exercise.
